Ball Rail Systems

Bosch Rexroth offer a comprehensive range of ball rail systems. These allow the user to combine guide rails and runner blocks in a number of versatile ways.

Their ball rail systems offer high load capacity and extreme rigidity at all levels of accuracy, and are suitable for use in virtually any task involving precision linear motion.

Ball rail systems in miniaturized configuration
These products are designed for any application that calls for ball rail systems of extremely small size and high load capacity.
The wide range of Rexroth mini ball rail systems covers sizes 7, 9, 12, 15 and 20 mm, and is available in widths of 9, 12 and 15 mm.

Ball rail systems with integrated measuring system
The integrated measuring system for ball rail and roller rail systems consists of a scanner (probe) with sensor system pinned to the runner block and a steel scale built into the rail. Machine malfunctions are thus kept to a minimum.
